DESCRIPTION AND OPERATIONAir Knob
GENERAL DESCRIPTION OF SYSTEMTurning the AIR knob clockwise operates the three-
speed blower motor.
The air &mditioner is intended to give maximum
cooling comfort within the vehicle. To do this, care-
ful attention must be given to the following sections.
The system operates on recirculated air only and is
entirely @dependent of the vehicle heater.Temp Knob
Recirculated inside air is drawn into the unit, passed
through the evaporator core and into the car through
the adjustable outlets in the duct assembly.This knob may be regulated to cohtrol the degree of
cooling desired. Fully clock-wise provides maximum
cooling; however, turning the kndb to the center de-
tent position provides adequate cooling for highway
operation.
CONTROLSWhen maximum cooling is reqlired, outside air
should not be admitted to the car.
System c&trols are the AIR knob controlling the
three
spe&d blower motor switch and the TEMPWhen the unit is set for maximum cooling and the
vehicle is being driven continuously at highway
knob which controls the setting of the thermostaticspeeds or at elevations of 4,000 ft. or more, there is
switch. When operating this system, the heater musta possibility of the formation of ice on the evaporator
be off for maximum cooling.core tins.

5. If the low side pressure was less than the pre-
scribed pressure at the end of each cooling cycle, turnthe adjusting screw a partial turn clockwise. See Fig-ure 9B-192.AIR CONDITIONER SYSTEM
- GT9B- 99
CONNECTOR
Figure 98.192 Adjusting Thermostatic Switch6. If the pressure was more than the prescribed
value, tuin the adjusting screw counter-clockwise.7. Reinstall switch end plate and install switch in
face plate. Install face plate on evaporator assembly
assuring
,that the air sensing capillary has been re-
placed properly.
Figure 98-l 93 Vacuum Switch8. Check system performance. Iffurther adjustment
is needed, repeat steps 3 thru 7 until the correct
pressure is reached.
REMOVAL AND INSTALLATION OF BLOWER
SWITCHDo not attempt to run a performance test with the
duct assembly and switch removed from the
evaporator assembly
- inaccurate readings will re-
sult. Always replace the switch and duct assemblies
before c+ecking the system performance.
